Bridge pier column integral hoisting reinforcement cage rapid positioning installation construction method
The invention relates to a rapid positioning and mounting construction method for a bridge pier column integral hoisting reinforcement cage. The method comprises the following steps that S1, the bridge pier reinforcement cage is manufactured in advance; s2, a bearing platform foundation pit is excavated, and pier bearing platform steel bars are installed in the bearing platform foundation pit; s3, plane positioning stirrups are bound on the pier bearing platform rebar surface layer rebars according to the positioning axes; s4, a pier reinforcement cage is hoisted and placed in the plane positioning stirrups; s5, a corner rib of the front vertical face of the bridge pier reinforcement cage and a bottom supporting rib are welded in a lap joint mode; s6, the other corner rib of the front vertical face of the pier reinforcement cage and the bottom supporting rib are welded in a lap joint mode; s7, the corner ribs of the side vertical faces of the pier reinforcement cage and the bottom supporting ribs are welded in a lap joint mode; s8, the four corners of the pier reinforcement cage are connected with the steel chisels through cable-stayed steel wire ropes; and S9, dismounting the hoisting steel wire rope. The pier reinforcement cage is manufactured in advance and then integrally hoisted and installed, a construction platform does not need to be erected, the pier reinforcement cage does not need to be bound on site, the engineering amount is small, the construction efficiency is high, and the quality of the pier reinforcement cage can be guaranteed.
本发明涉及一种桥梁墩柱整体吊装钢筋笼快速定位安装施工方法，包括以下步骤：S1：提前制作桥墩钢筋笼；S2：开挖承台基坑，承台基坑内安装桥墩承台钢筋；S3：依据定位轴线在桥墩承台钢筋面层钢筋上绑扎平面定位箍筋；S4：吊装桥墩钢筋笼放入平面定位箍筋内；S5：对桥墩钢筋笼正立面其一角筋与底部支撑筋搭接焊接；S6：对桥墩钢筋笼正立面另一角筋与底部支撑筋搭接焊接；S7：对桥墩钢筋笼侧立面角筋与底部支撑筋搭接焊接；S8：桥墩钢筋笼四个角通过斜拉钢丝绳与钢钎连接；S9：拆除吊装钢丝绳。本发明通过将桥墩钢筋笼提前制作，再整体吊装安装，不用搭设施工平台以及现场绑扎桥墩钢筋笼，工程量小，施工效率高，且能保证桥墩钢筋笼的质量。
